9318. 'Nor serve them' means that neither must they be obeyed. This is clear from the meaning of 'serving' as obeying, dealt with in 8987, 8991, and also worship, 7934, 8057.

7934. 'That you shall keep this service' means worship because of the deliverance. This is clear from the meaning of 'keeping' as that which is to be observed, as above in 7930a; and from the meaning of 'serving' or 'service' as worship of the Lord.
